Erratum: Search for anomalous $ t\overline{t} $ production in the highly-boosted all-hadronic final state

Abstract

The first paragraph on p. 15 of the original version should be replaced by the following paragraph, which deletes an incorrect reference to a figure.The uncertainties on the mistagged NTMJ background include the statistical uncertainty on the sample after loose selection, to which the mistag probability is applied; the statistical uncertainty on the mistag probability itself, ranging from <1% at 1 TeV/c 2 to ≈10% at 3 TeV/c 2 ; and the systematic uncertainty on the mistag probability application, as described in section 3.3, which is in the range of 1 to 5% depending on the tt mass. The total background uncertainty is ≈5% for the low-mass region, dominated by the systematic uncertainty, and ≈100% for the high-mass region, dominated by statistical uncertainty associated with the sample after loose selection.

“…These mass limits represent significant improvements over previous ones set at √ s = 7 TeV [26,29,30]. An improvement by about 50% on the 95% CL upper limits with respect to an earlier search optimized for high masses at √ s = 8 TeV [31] is achieved by the application of additional jet substructure information and the addition of the dilepton channel.…”

“…Direct searches for heavy tt resonances have been performed at the Fermilab Tevatron and the CERN LHC colliders, with no evidence for such signals. The experiments at the Tevatron have probed the mass range up to about 900 GeV [20][21][22][23][24][25], using the leptophobic Z model, and the LHC experiments have set subpicobarn limits on the production cross section in the mass range of 1-3 TeV [26][27][28][29][30][31].…”

“…Previous searches at the Fermilab Tevatron have excluded a leptophobic Z boson up to 900 GeV [19][20][21][22][23][24] at 95% confidence level (CL). Experiments at the CERN LHC have excluded various Z and g KK models at 95% CL in the 1-4 TeV mass range [25][26][27][28][29][30][31][32]. The results presented here represent a significant improvement on the previous searches for tt resonances.…”
